Assume that you use Microsoft BizTalk Server in Windows Server 2012 or Windows Server 2012 R2. When you try to use the File Adapter while you are using alternate credentials, you receive the following error messages:
Error 1219 (0x800704c3)
'The Messaging Engine failed to add a receive location "Receive Location1" with URL "\\fileservername\sharename\*.*" to the adapter "FILE". Reason: "The FILE adapter cannot access the network share using the supplied credentials. URL: \\fileservername\sharename\ Error: Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again. ". '
